How far ahead can the tide be predicted?
The tides are generated by gravitational influences of the Earth-Moon-Sun system, whose astronomical relationship and orbital details are known extremely accurately. Using this information, together with the tidal constants derived from the tidal analyses, the tides can be predicted for any date as far ahead into the future as required.
Since the tide is caused by the astronomy of the earth-moon-sun system which is known very accurately and can be predicted well into the future, the tides can also be predicted well into the future. So if you want to plan your sailing club events for the next year, get in touch and (for a small fee) Applications Team will provide you with the tide table. When trying to predict well into the future, we have to take into account the rise in global sea level. The further into the future we try and predict, the more significant this effect can become.
The tides are generated by gravitational influences of the Earth-Moon-Sun system, whose astronomical relationship and orbital details are known extremely accurately. Using this information, together with the tidal constants derived from the tidal analyses, the tides can be predicted for any date as far ahead into the future as required. However, for predictions well into the future (many decades) the effects of global sea level rises and changes in seabed topography have to be carefully considered. These may have a significant effect upon local tidal behaviour, and the predictions can only be computed using the tidal data currently available on the UKHO database. So the further ahead we go from the date the tidal data is held on the database, the less reliable the predictions will become. Q What are “Spring” and “Neap” tides? Spring and Neap tides are created by the relationship between the Earth and the Moon during each lunar month. Spring tides occur shortly after New and Full Moon,

What causes tides? Tides are caused by the effects of gravity in the earth-moon-sun system, and the movement of those three bodies within the system. If you imagine that the earth is completely covered in water, there are two bulges of water – one towards the moon and another on the opposite side (see question 4). The rise and fall in sea-level is caused by the earth rotating on its axis underneath these bulges of water. There are two tid
